Hi, We are hiring for a Backend Platform Engineer for our client in TX/Dallas.Candidate must be available to attend FTF client interview.
*Location*: TX/Dallas(Hybrid) *Max Rate*: $75 *Description Of Services*: IIoT Platform (On Prem Kubernetes, MQTT, TimescaleDB, Schema Registry) About the role develop the backend of Nexus: build resilient microservices that speak MQTT, enforce data contracts via Forge, and deliver high throughput, reliable ingest into TimescaleDB on on prem Kubernetes. Drive service SLIs/SLOs, security, and multi tenant operations. Partner with OT (often via Ignition) while keeping the focus on backend reliability and developer experience. Optional secure hybrid to AWS for backup/analytics. Key responsibilities Backend services and APIs o Build stateless, performant services (Go/Java/Python) for ingest, validation, enrichment, and persistence. o Define versioned contracts (REST/gRPC), ensure backward compatibility, idempotency, and robust retries. o Provide shared libraries for schema validation, authN/Z, tracing. MQTT messaging o Implement producer/consumer services with QoS 0/1, retained messages, shared subs, session persistence. o Design tenant aware topic hierarchies, ACLs, and secure device onboarding. o Enforce TLS/mTLS, certificate rotation; optimize throughput with batching and backpressure. Data contracts (Forge) and CI enforcement o Model telemetry/events with JSON Schema; strict compatibility rules and gated CI checks. o Validate in the data plane; route bad payloads to DLQ with replay tooling. o Lead producer/consumer versioning and migrations. Time series storage (TimescaleDB) o Design hypertables, compression, retention; high throughput ingest with ordering, dedupe, upserts. o Optimize reads via continuous aggregates and indexes; own backup/restore and PITR. On prem Kubernetes o Ship Helm charts; manage Deployments/StatefulSets, HPA/VPA, probes, resource tuning. o Establish end to end observability (metrics/traces/logs), actionable alerts; GitOps for promotion/rollback. Security, multi tenancy, and reliability o Zero trust defaults: mTLS, RBAC hardening, network policies, per tenant isolation. o Secrets/PKI management (Vault/KMS), audit logging; ingress/egress controls and rate limits. o Define SLIs/SLOs; canary/blue green, chaos testing; runbooks, on call, post mortems; DLQ/quarantine and replay. Collaboration and delivery o Strong PR hygiene, branch protections, semantic versioning, release tagging in GitHub. o Document ADRs, runbooks, and APIs; align OT tag models/payloads with backend contracts. Required qualifications 5+ years building production backend services in Go/Java/Javascript/C/Python. Deep MQTT understanding (EMQX/HiveMQ/Mosquitto): QoS 0/1, retained, shared subs, sessions, ACLs, TLS/mTLS. On prem Kubernetes or docker: Helm, compose, observability, autoscaling, GitOps, secure multi tenant ops. Time Series Database/historian: hypertables, compression, retention, continuous aggregates, performance, backup/restore. Schema registry with JSON Schema; CI enforced compatibility. CI/CD (GitHub Actions or similar): build/test, canary/blue green, artifacts, automated rollbacks. Security: PKI, certificates, least privilege, network segmentation, Vault/KMS, audit logging. Nice to have Ignition (Transmission/Engine), OPC UA/Modbus/EtherNet/IP. Kafka/Pulsar and MQTT bridges; CDC/outbox patterns. IaC (Terraform/Ansible), Rancher/OpenShift; edge (K3s). Service mesh (Istio/Linkerd) for mTLS/traffic policy. Hybrid AWS for backup/analytics (ECR/S3/Glacier, secure tunneling). *Deliverables*: -Process Flows -Mentor and Knowledge transfer to client project team members -Participate as primary, co and/or contributing author on any and all project deliverables associated with their assigned areas of responsibility -Participate in data conversion and data maintenance -Provide best practice and industry specific solutions -Advise on and provide alternative (out of the box) solutions -Provide thought leadership as well as hands on technical configuration/development as needed -Participate as a team member of the team -Perform other duties as assigned Full Legal Name Contact Information Work Authorization Status Copy of Work Authorization Current Location Willingness to Relocate Availability to Start Expected Rate 2 Professional References LinkedIn Profile FTF Interview available dates & Time Last 4 digits of SSN Driving License Copy Passport copy *Thanks,* *Lyra Dass* *Human Resources ManagerDigital Resource Partners LLC* *+1(945)248-3020* *https://drpscorp.com/ <https://drpscorp.com/>* -- You received this message because you are subscribed to "rtc-linux".
